Product Details Supplier Info More products

Wolfson Microelectronics has introduced the WM8962, an ultra-low-power stereo audio hub designed to deliver crystal-clear audio to portable digital applications such as e-readers, tablets and more.

The WM8962 is also ideal for use in multimedia mobile phones, games consoles and digital still cameras and camcorders.

Highly flexible analogue mixing options, multiple onboard clock generators, high-performance ADCs and DACs, and support for multiple analogue and digital microphones enable the WM8962 to support a range of use cases in multiple consumer electronics applications.

Its flexible audio enhancement digital signal processor (DSP) features multiple preset algorithms.

Virtual Surround Sound widens the stereo speaker audio range, providing a richer, immersive listening experience.

HD Bass intelligently enhances low frequencies, boosting the frequencies that small speakers can reproduce, without increasing the lowest frequency signals that small speakers cannot reproduce.

Retune flattens the frequency response of the speaker or microphone path to maximise the performance of the transducer.

A configurable DSP also includes functions such as 3D widening for recording, a five-band parametric equaliser and a dynamic range controller.

Utilising an integrated charge pump and ground-referenced output, the WM8962 features a Wolfson Class-W ultra-low-power headphone driver, designed to optimise efficiency and power consumption while reducing DC ground offsets and minimising pops and clicks.

The WM8962 incorporates a stereo Class-D speaker driver, which provides 1W per channel into 8ohm loads, or 2W mono into a 4ohms load, with a 5V supply.

Low leakage, good power supply rejection ratio (PSRR) and pop/click suppression mechanisms also allow direct battery connection to the speaker supply.

The WM8962 is available for sampling in a W-CSP, 3.6 x 3.9mm 49-pin package.

WM8962 customer evaluation boards are available to aid device evaluation and development.
